Fix the runs will not be displayed bug when the main branch have no workflows but other branches have (#28359) (#28365)

Backport #28359 by @lunny

The left menu will only display the default branch's workflows but the
right side will display the runs triggered by all branches' workflows.
So we cannot hide right side if default branch has no workflows.

Fix #28332
Replace #28333
