Bring coverage to 100%

[nicolasspring]

This small PR should increase test coverage to 100%. This is done in three main ways:

• Adding explicit tests for AcquisitionStage._should_skip_extraction() and AcquisitionStage._extract_zip() to cover handling of exceptions and edge cases.
• Testing main() in geoparser/__main__.py via subprocess. Because this cannot be tracked by coverage in the parent process, the line is excluded from coverage nonetheless.
• 2 additional lines with exception handling for disabling extensions (spellfix and spatialite in loader.py) are also excluded. These exception handlers guard against SQLite-internal failures. This allows us to exclude them in my opinion, as mocking such exceptions is a bit out of scope for this Python test suite. Feel free to challenge.
