Separate the unit tests from the post build tests

[YonatanKra]

Currently, the test command runs all tests.
The problem is - some tests are unit tests, and some are relevant only after a new build.
The post build tests reside in the src/askscript/__test__.
Unit tests are all the rest.
Need to separate the two types of tests.
Maybe even take out the post build tests outside the src folder.
