Bug 195/add vector layer

[zacdezgeo]

What I Changed

• Moved fixtures to contest so we can reuse with multiple tests files
• Define tests on vector geometries
• Fix bug by defining the provider used upon layer creation

How to test it

• Run the test suite: python3 -m pytest test
• Checkout our CI

Other notes

• closes Error after layer is added  #195
• Thanks for the investigative help @alukach 💯

Commenting for future 👀: So the practical impact here is that we are treating all Earth Engine data as a QgsRasterLayer layer registered with the "EE" provider which is managed via our custom EarthEngineRasterDataProvider.
