tui: fix requesting and displaying secrets

Browse source 
nmt_sync_op_complete_pointer() completes the operation after the
caller of this function returns.  This means that any values passed
to this function must either be allocated from its caller, or
referenced by the caller.

nm_remote_connection_get_secrets() owns the 'secrets' hash passed
to the callback, and it is destroyed when the callback returns.
So nmtui's got_secrets() must copy the hash to ensure the data
sticks around for nmt_sync_op_wait_pointer() later.
