MAINT: Remove parameters from test that tests lack of parameters.

The `test_multi_source_as_input_no_start_end` test is designed
to test for a lack of simulation parameters, so make that they are
not passed.

Was unnoticed because sim_params passed as an arg are dropped.
BUG: Ensure algorithm tests use test simulation parameters.

To pass sim_params to TradingAlgorithm using kwargs is required.
When just passing sim_params as an arg, it was ignored.
