[Coverage]: Add advanced tests for transaction subsystem configuration

[OndrejGerzicak]

Description

The basic tests migrated from legacy TS doesn't seem to be complex enough, see #34 and #96.

We should also be testing:

• Invalid input values
• Invalid scenarios when some attribute cannot be written when other one is not set, etc.
• Consider adding Reset test
• Consider how to handle coverage for /subsystem=transactions/commit-markable-resource and /subsystem=transactions/log-store
