Break up _pyrepl tests

[eugenetriguba]

I'd like to work on increasing the test coverage of the new _pyrepl module:

 % ./python.exe ../coveragepy report --show-missing

However, with all the tests in the single file, it was seeming like it'd start to get unwieldy. As a first step, I'd like to break this test_pyrepl.py file apart.
