tags-cache: skip the filternode step if we are not going to use it
When warming the hgtagsfnodescache, we don't need the actual result, so we can
simply skip the part that "filter" fnode we read from the cache. So provide a
quite visible speed up to the top level `hg debugupdatecache` function.

Test repository filtering avoidance
===================================
This test file is a bit special as he does not check feature, but performance related internal code path.
Right now, filtering a repository comes with a cost that might be significant.
Until this get better, ther are various operation that try hard not to trigger
a filtering computation. This test file make sure we don't reintroduce code that trigger the filtering for these operation:
Setup
-----
$ hg init test-repo
$ cd test-repo
$ echo "some line" > z
$ echo a > a
$ hg commit -Am a
adding a
adding z
$ echo "in a" >> z
$ echo b > b
$ hg commit -Am b
adding b
$ echo "file" >> z
$ echo c > c
$ hg commit -Am c
adding c
$ hg rm a
$ echo c1 > c
$ hg add c
c already tracked!
$ echo d > d
$ hg add d
$ rm b
$ cat << EOF >> $HGRCPATH
> [devel]
> debug.repo-filters = yes
> [ui]
> debug = yes
> EOF
