Fixes #470

Cached value may or may not be a class info. Previous calls to GetAnalysisValueFromObjects may have cached a different object for the type. For example, IPythonFunction would cache BuiltinFunctionInfo and not BuiltinClassInfo.

Before #439 it worked since IPythonFunction and IPythonClass were not IPythonType and in GetAnalysisValueFromObjects IPythonType was handled first so the cache would always contain item created for IPythonType as the first in the order of processing. This is no longer true.

The fix is not ideal, another approach is to create different caches for different types.

Sorry, something went wrong.

Cherry pick fixes from Release branch into PTVS branch (#578)
a5b6e5e
* Fix #470 (#478)

* Fix various common exceptions, log on a failed directory load (#498)

* rethrow exception after telemetry instead of disposing

* log an error instead of crashing when hitting some exceptions loading files, fix nullref when shutting down without an idle tracker

* fix short circuiting of question mark checks to prevent null from being returned

* print name of exception instead of relying on ToString

* don't use MaybeEnumerate

* upgrade message to Show

* Mitigate some of #495 via MRO member selection and analysis set optimization (#517)

This isn't a complete fix, but does seem to improve #495 in some cases. Adds back the early MRO return removed in #277, so now large class hierarchies won't over-propagate types (where some of the trouble with fastai happens do to the Transform class). I also optimized AnalysisHashSet a little to do length checks when possible.

There are still times when things get caught up comparing unions for a while, but it seems to be nondeterministic.

* Two path resolution bug fixes

- Fix #509: PLS doesn't flag error in a relative import if it is found in another root directory (#519)
- Fix #510: PLS doesn't resolve relative paths correctly

* Catch exceptions when importing from search paths (#525)

* catch exceptions when importing from search paths

* retry instead of not found
