fix(files): show 'N tag(s)' instead of 'N folder(s)' in systemtags view

Tags are represented as Folder nodes with an 'is-tag' attribute set by
the systemtags app. getSummaryFor now detects these and uses the
'systemtags' translation domain for the count, so the footer reads
'1 tag' rather than '1 folder'.
