fix: invalid forced sync peer now returns configerror (#3350)

Description
---
Fixed bug which returned an UnknownError instead of a ConfigError for invalid force sync peers.
Remove double print of error.

Output:
```
Running `target\debug\tari_base_node.exe`
Initializing logging according to "C:\\Users\\DMStrider\\.tari\\config\\log4rs_base_node.yml"
Please check your force sync peers configuration
ConfigError("Invalid force sync peer: Invalid public key string")
14:43 ERROR Exiting with code (101): ConfigError("Invalid force sync peer: Invalid public key string")
```
Motivation and Context
---
Previously an UnknownError was reported for invalid force sync peers

How Has This Been Tested?
---
Configuration with invalid force_sync_peers.
