api tests: add store fixtures

Prior this commit there wasn't an easy to populate the store. The only way
was to call the weldr API or store methods. This design made testing of
various edges quite hard.

This commit adds store fixtures - an easy way how to define store state
before each test case.

In addition, the fixtures were refactored so that new instances are created
prior each test. Before this change the tests were in some cases dependant
on each other.
