generaldelta: initialize basecache properly Previously basecache was incorrectly initialized before adding the first revision from a changegroup. Basecache value influences when full revisions are stored in revlog (when using generaldelta). As a result it was possible to generate a generaldelta-revlog that could be bigger by arbitrary factor than its non-generaldelta equivalent.
