- close hyphenationTest window.
- properly close zoteroPane window in preferences_syncTest.
after() hook inside of the test would not close the window until the
very end of the entire test run. Without this, during
subsequent tests that open their own zoteroPane window, there
are two instances of zoteroPane open at the same time.
- close open tabs in readerTest cleanup, since subsequent
tests expect library tab to be selected.
