refs #10571
- Removes dependency on 'context' property being set in error when
checking a theme
- Refactoring was needed to be able to avoid passing checked theme as a
part of thrown error (logic was relying on error having this specific
data in context property). This created a problem where we controlled
the logic flow with data in error object.
- Introduced 2 different types of theme check handling, one behaves the
same way as before, the other gives more granulac control to the caller
to decide what to do with returned errors.

GScan can return errors, which was not handled in our theme validator and caused Ghost to crash completely. GScan will now return an Ignition error when its not able to read the `.zip` file.
e. g.: `{"errors":[{"message":"Failed to read zip file","context":"tife.zip","errorType":"ValidationError","errorDetails":"invalid relative path: ../tife/"}]}`
