Do the same as in case of "Deploy" string: after
restoring overwrite it with proper translated string.
Side note: tr("Build") and tr("Clean") have already
been used inside buildconfiguration.cpp so it will
not produce a new record in .ts file, i.e. this
change is not introducing a new message in string freeze
period.
