An example of the bug

~~Unfortunately I don't have a sample atm~~

Expected vs actual behavior

MockMiddleware{Index} to be destroyed if not in cacheDeclaration

Misc

I am on the latest 14.12.1 I haven't been able to update ng-mocks since 14.9.0. Upgrading to 14.10.0 and later gives me this issue.

I get the following CI, but it's fine locally.

Instincts to points to memory leak.

This and the other bug reported today, I believe, are the causes.
