Resolve definitions.py fix to fix backwards compatibility break in plugins

[usingtechnology]

Include searching by the module base package when resolving plugin definitions location.

Fixes #2224

This still depends on the module package names and file system paths matching up, which is not guaranteed. But without adding additional configuration in the plugin registry, I think this is all we can do.

One minor comment. I'll follow up on testing with the example plugin I referred to #2224 in response to your comments on the same issue!

@dbluhm — not clear on your comment above. Do you want to test the #2224 issue before we merge, or are you good with the solution we have?

[dbluhm]

I am hoping to test myself first -- not that I don't trust the fix lol just want to verify the fix and my understanding before calling it good. I can run it through a couple of plugins in addition to the minimal example provided in #2224

[dbluhm]

Tested and working for at least one of our plugins that was previously broken. Thanks!

@dbluhm — should this trigger a new release — presumably 0.8.2?

[dbluhm]

Yes
