Description of the issue: one corrupted Git repository makes the Radicle node unable to start up with an error such as below:

failed to parse loose object: invalid header; class=Object (11)

Removing the corrupted repository from the storage path makes it possible to start the node again.

Expected result: a single corrupted Git repository should not affect availability of the node itself.

Actual result: the corrupted Git repository made it impossible for the node to start.
