Unify the assertions look for all tests

For consistency, now all tests follow the following:
1. all assertions are in double square quotes like [[ .... ]]
2. left part of the assertions is described without quotes
3. all variables are in ${...} format

-- `[[ "$status" -eq 2 ]]` for a command status
-- `[[ "${#lines[@]}" -eq 0 ]]` for a length of command output

-Use the following test name template - `'<command args>': <describe what will be tested>` like
-`'clone-repository': raise an error if cloneable URL isn't set`.
+Use the following test name template - `'<command>': <describes the behavior that will be tested>`

+The behavior should be descriptive-style (`stops with exit code 45 if cloneable URL is not set`)
