"get_schain_status" function returns different types

[oleksandrSydorenkoJ]

Describe the bug
The "get_schain_status" function returns String for error messages and Dict for success calls

skale-checks/skale_checks/adapters/watchdog.py

Line 111 in c61a905

def get_schain_status(self, schain_name):

Version:
skale-checks:1.0dev17

Preconditions
Schain Medium type
All nodes are up and running

To Reproduce

1. Connect the Watchdog checks from the Skale-checks
2. Invoke get_schain_status for node A from the Skale chain
3. Stop skaled-container for chain on this node A
4. Invoke get_schain_status for the Skale chain on stopped node A

Expected behavior
Skaled in steps 2 and 4 should return the same Dict type:

• For running skaled should return the actual Skale chain status
• For stopped skaled should return empty Dict

Actual state
Skaled in steps 2 and 4 returns:

• Dict with skaled Statuses
• String with error message "sChain <schain_name> not found"
