typing: disable some pytype errors in `mercurial.store`

These seem to be legitimate errors, since one of the two callers
(`encodedstore.data_entries()`) was previously typed to generate
`BaseStoreEntry`.  However, that and the other caller only pass
`RevlogStoreEntry` objects.  I can't tell if this was a WIP or what, but don't
want to get side tracked on this.  So flag as a TODO for later.
