Merge let-tests-run-under-python-O-4476: installReactor() does not use assert.
Authors: ivank, screwtape
Reviewers: screwtape, exarkun
Fixes: #4476
twisted.internet.main.installReactor() used to "assert" that no previous
reactor was installed, but "assert" statements are compiled out when
Python runs with the "-O" parameter, which enabled Twisted's test suite
to try installing multiple reactors with no happy result.
Now installReactor() uses an ordinary "if" statement instead of
"assert", and Trial no longer crashes when running the Twisted test
suite in "python -O" mode.
