ui: check for progress singleton when clearing progress bar (issue5684)

A combination of wrapping `ui` and progress bars interrupted by exceptions can
lead to the progress bar not being cleared when the exception error is printed.
This results in corrupted-looking output like this:

```
updating [===============================>                        ] 1/2u
nresolved conflicts (see hg resolve, then hg rebase --continue)
```

This is because in `ui._progclear`, we only check the local reference to the
progress bar, not whether or not there is an instance of the singleton.  When a
progress bar is interrupted by an exception, the exception printing in
`scmutil.callcatch` uses the original instance of the `ui` object, not the
wrapped copy that has `_progbar` set.

When consider whether or not to clear the progress bar, check for the existence
of the singleton, rather than just whether or not we have a local reference to
it.

 Unfortunately, subrepos not at their nominal location cannot be cloned.  But
 they are still served from their location within the local repository.  The only
 reason why 'main' can be cloned via the filesystem is because 'sub1' and 'sub2'
 are also available as siblings of 'main'.

 Check that deep archive works with largefiles (which overrides hgsubrepo impl)
 This also tests the repo.ui regression in 43fb170a23bd, and that lf subrepo
 subrepos are archived properly.
 Note that add --large through a subrepo currently adds the file as a normal file
