fix: issue where could not have dependencies with contracts_folder pointed at the root project path

[antazoey]

What I did

fixed a bug where could not compile dependencies like:

dependencies:
  - name: b64
    github: Brechtpd/base64
    ref: main
    contracts_folder: .

issue: it got turned to "" via a bad replace during a config manifestation.

How I did it

if the paths re equal, make the temp config value for contracts_folder be "."

NOTE: This all makes so much more sense on the project refactor for 0.8 .... just sayin! But this is a solid fix for the 0.7 range I think.

ALSO: I purposely made the test an integration test to ensure this carries over to 0.8 because any functional test would likely get erased (so I didn't add any of those).

How to verify it

Use this config:

dependencies:
  - name: b64
    github: Brechtpd/base64
    ref: main
    contracts_folder: .

and run:

ape pm install .
