LockSettingsShellCommand: improve an error message
Show an appropriate error message when trying to set a lock credential
when the user already has one and the old credential wasn't provided.
Previously the empty credential got passed down to
LockPatternUtils#checkCredential(), resulting in an error of
"Credential can't be null or empty" which was confusing in this context.
