Fix GROUP BY clause in Special:MostLinkedTemplates

This only cause a trouble for Microsoft SQL which require the column to be
referenced by their input name, not the output one (AS alias). Might trigger
on Oracle database.

This is part of bug 31913: 'GROUP BY clauses incorrect in SQL generated
for special pages'

Need backport in REL1_18
