[CI-SKIP] Avoid rebuilding Paper-Server if Paper-API did not apply
This scenario occurs when Paper-API fails, we then rebuild the patches,
however Paper-Server was left un an outdated state since the most
recent patches did not get applied to it.

This results in us reverting Paper-Server to an older state.

If Paper-API fails to apply, then Paper-Server has to be considered dirty.

This should avoid us having accidental patch reversions
