Aaron Gyes fc9d8eec72 history expect tests: fix the tests.
The colors happening for the interactive tests didn't match the
expected output. For `history search` commands we test, have them
pipe through `cat` so the fishscript does not use a pager or try
to colorize.

# This is a very fragile test. Sorry about that. But interactively entering
# commands and verifying they are recorded correctly in the interactive
# history and that history can be manipulated is inherently difficult.
#
# This is meant to verify just a few of the most basic behaviors of the
# interactive history to hopefully keep regressions from happening. It is not
# meant to be a comprehensive test of the history subsystem. Those types of
# tests belong in the src/fish_tests.cpp module.
#
# The history function might pipe output through the user's pager. We don't
# want something like `less` to complicate matters so force the use of `cat`.
