Agent Saves Registration Information Even on Failure

[vikman90]

Parent Issue: #241

Description

When attempting to register an agent and the process fails with errors such as:

Failed to authenticate with the manager
wazuh-agent registration failed

The agent still creates and populates the agent_info.db file:

select * from agent_info;
dummy|ku3iIzPRNJjwIXKNnTU3qFv6QhodAu8k|95635cae-0c0d-486e-94a5-0fe29dd6972f

Steps to Reproduce

1. Attempt to register the agent with invalid credentials.
2. Observe the error messages in the logs.
3. Check the contents of the agent_info.db file.

Expected Behavior

If the registration process fails, the database should not be altered.
