Marius Gedminas 54eae4a793 Check sys.modules before loading modules
Code for a plugin is usually loaded by a PluginLoader(), and henceforth
available from self._module_cache, which prevents duplicate loading.
However there are situations (e.g. where one action plugin imports code
from another one) where the plugin module might be already imported (and
resident in sys.modules), but not present in the PluginLoader's
_module_cache, which causes imp.load_source() to effectively reload the
module, overwriting global class declarations and causing subtle latent
bugs.

Fixes #13110.
Fixes #12979.
