Subject: QTranslator: enable NRVO in find_translation() for poor compilers

... such as GCC.

truncate(0) was chosen because it is already used throughout
the function. Using clear(), say, which is inline, produces
slightly more code.

As is, saves 160b in text size on optimized GCC 4.9 Linux
AMD64 builds.
