Subject: [PATCH] Disable plugin autoloading in the test suite
Disable plugin autoloading in the test suite to prevent other installed
plugins from interfering with the test results. This is particularly
important since tests are run with cleared environment that could break
other plugins (e.g. pytest-xvfb is broken by the lack of PATH).
Fixes #48
