tags: don't read .hgtags fnodes from tags cache files

Now that we have a standalone and shared cache for .hgtags fnodes, the
.hgtags fnodes stored in the tags cache files are redundant.

Upcoming patches will change the format of the tags cache files to
remove this data and to improve the validation. To prepare for this, we
change the tags reading code to ignore all but the tip .hgtags fnodes
entries in existing tags cache files.

All fnodes lookups now go through our new shared cache, which is why
test output changed. Format of tags cache files has not yet changed.

Add a merge with one parent in the same branch

  $ echo a >> a
  $ hg ci -qAm changea
  $ hg up -qC 0
  $ hg branch branch0
  marked working directory as branch branch0
  (branches are permanent and global, did you want a bookmark?)
  $ echo b > b
  $ hg ci -qAm addb
  $ hg up -qC
  $ hg merge default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -qm mergeab
  $ hg tag -ql mergeab

Miss perl... sometimes

Add a merge with both parents and child in different branches

  $ cd source
  $ hg branch branch1
  marked working directory as branch branch1
  (branches are permanent and global, did you want a bookmark?)
  $ echo a > file1
  $ hg ci -qAm c1
  $ hg up -qC mergeab
  $ hg branch branch2
  marked working directory as branch branch2
  (branches are permanent and global, did you want a bookmark?)
  $ echo a > file2
  $ hg ci -qAm c2
  $ hg merge branch1
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg branch branch3
  marked working directory as branch branch3
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -qAm c3
