Circular Import errors on the latest version

[austinv11]

Describe the bug
There was a circular import error that I believe was introduced by this commit: 05f13be

This prevents me from making use of the omnipath database.

To Reproduce
Steps to reproduce the behavior:

from pypath import omnipath
op = omnipath.db.get_db('curated', ncbi_tax_id=9606)   # Circular import error here

Expected behavior
No exceptions

Traceback
