Fix: Filter out in construction buildings for totalunitlevels (#2580)

## Description:

Fix for v28.

After PR #2378 changes, unit type Construction doesn't exist anymore.
Resulting in totalUnitLevels counting in construction buildings towards
total units in TeamStats, old and new Build Menu and Player Info
Overlay. To fix this we now need to filter out the construction phase.

totalUnitLevels is only used for displaying total count purposes, it
doesn't affect other logic.
