Local scope imports error if using pytest hot reloader

[JamesHutchison]

When doing a local scope import

def my_func()
   from foo.bar import Moo

Using MegaPatch.it will error

MegaPatch.it(Moo)

This appears to be because the name is recorded by the import machinery as part of the module its imported in, but it doesn't actually show up in the namespace of the module, which creates the error. The likely solution to this problem is to have the import machinery ignore these imports.
