vcxproj file contains incorrect primary output filename

If VERSION is set in the qmake project which is being built for win32-msvc2013 (or 2012, or 2010 I suspect), qmake sets the PrimaryOutput in the project file to include the major version, but the actual .exe filename generated does not contain the major version.

With this simple project file

TEMPLATE = app
TARGET = versiontest
VERSION = 5.0.0.0

SOURCES += main.cpp

The resulting vcxproj file says:

<PrimaryOutput>versiontest5</PrimaryOutput>

but in the linker section:

<OutputFile>$(OutDir)\versiontest.exe</OutputFile>

So the project won't run from the IDE, because versiontest5.exe does not exist.

msvc_vcproj.cpp:919 is responsible for this but it's not clear why it does it for applications, seems to be only useful on shared libraries. Or at least the linker output filename should match.
