Clean the repository cache if it is in incomplete state

[lufia]

Go-git v5 has PlainCloneContext. It accepts a context.Context at first argument then it cleanup the directory if any error is occurred in cloning the repository.

ref #538 (comment)

Seems like this issue occurs when actions cache gets corrupted.
