When opening a repository, it will call `ensureValidRepository` and also `CatFileBatch`. But sometimes these will not be used until repository closed. So it's a waste of CPU to invoke 3 times git command for every open repository. This PR removed all of these from `OpenRepository` but only kept checking whether the folder exists. When a batch is necessary, the necessary functions will be invoked.
