fix(admin-cli): fix the command reports incorrect ERR_INVALID_PARAMET…

…ERS error (apache#1699)

apache#1698

Do not set the `backupPath` field of `StartBackupAppRequest` if it's not set
to avoid an `ERR_INVALID_PARAMETERS` error from server. The error is caused
by a conflict check on server side between `StartBackupAppRequest.backupPath`
and `[block_service.hdfs_service].{args}`, the latter has defined a default
backup path.
