Andrew DanielsandGitHub ba484e5469 MAINT: Removes unnecessary capital_base arg to TradingAlgorithm (#1677) 
Capital base is included in the sim params, so we should define the
value there, or use the default.

This change also unifies the default capital base as 1e5, as was
previously defined in algorithm.py.

Andrew Liang 97f537f35c TEST: Allow parameter_space to work on repeated calls of test 
If we have a test that's being called more than once (i.e. two
test cases, both subclasses of the same base test case, with
different setup but calling the same test), allow the subsequent
calls to re-consume the same params

Scott Sanderson bd7f3ad100 MAINT: Raise LookupError instead of KeyError. 
KeyError calls __repr__ on its input, which makes it really unpleasant
to read multi-line strings.

Scott Sanderson b2bacec241 ENH: Align daily/minute bar lookbacks by default. 
When EQUITY_DAILY_BAR_SOURCE_FROM_MINUTE is set, use
EQUITY_MINUTE_BAR_LOOKBACK_DAYS as the default value for
EQUITY_DAILY_BAR_LOOKBACK_DAYS.

Without this, trying to run a minutely backtest in a test setting only
EQUITY_MINUTE_BAR_LOOKBACK_DAYS and EQUITY_DAILY_BAR_SOURCE_FROM_MINUTE
fails because the benchmark creation process makes a daily history call
for the entire period of the backtest, which then fails because the
equity daily bar calendar is shorter than the equity minute bar
calendar.

I can't imagine a circumstance in which you'd want the daily bar
calendar to be shorter than the minute bar calendar when you're sourcing
daily bars from minutes, so this change makes that the default behavior
unless it's explicitly overridden.

Scott Sanderson e8b8b0afef BUG: Fix bad error handling in history loader. 
Fixes a bug where we'd fail to raise an error if the start/end of a
history window call don't aren't in the loader's calendar.

We were started dropping this error after a previous change swapped out
calls to `index.get_loc` with calls to `index.searchsorted` to avoid
creating hash tables in pandas.

Scott Sanderson 0c5f88e2f6 ENH: Add direct methods for session start/end. 
Rather than having to do 'start, _ = cal.open_and_close_for_session(dt)'
to get just the start, we can now do 'start = cal.session_start(dt)'.

Eddie Hebert 873f3a7fc9 BUG: Fix end session metadata for minute bar writer. 
When opening with a new `end_session`, i.e. opening for append, write the new
end session to the metadata.

Fixes an issue where the calendar on minute bar readers did not include the
recently appended day, causing reads on the last values to fail.

According, update append test to read a value, instead of checking table length.
