Backend: Import consistency of extension submodules

[MoritzWeber0]

I noticed that there is no consistency when importing submodules of a specific extension.
Extension modules usually have crud, models and routes as submodules.

Sometimes, imports are used in the way:

import capellacollab.extensions.<extension>.<submodule> as <extension>_<submodule>

and sometimes I see imports like:

import capellacollab.extensions.<extension>.<submodule> as <submodule>_<extension>

I prefer the second option. Are there any opinions about this?
