Fix ASV test failures and Installation Test Failures on Master (#2578)

#### Reference Issues/PRs
<!--Example: Fixes #1234. See also #3456.-->

#### What does this implement or fix?

ASV tests - ASV workflow does not contain Azure creds. Attempt to
extract azure creds failed due to unsafe usage of re.match().group

installation tests cannot include any package from arcticdb. Yet last
minute change symlinked mark.py file which indirectly contained such
include - hence tests failed.

Run from changed installation tests:
