dashboard/app: don't report bisections pointing to release commits

They should have been detected by "same binary" logic.
But the problem is that we may use different compilers
for different commits and they switch exactly at release commits.
So we can build the release with a differnet compiler than the
rest of commits and then obviously it won't be "same binary".
Detect release commits separately.

Update #1271
