Subject: [PATCH] bnc#798271: Don't delete the PropertyMapEntry instance
 prematurely.

When using comphelper::PropertyMapEntry array to create a UNO property
set, we need to make sure we keep this instance while the property set
object is alive, else it would cause a very hard-to-debug problem down
the road...

In this particular case, the aExportInfoMap array instance was destroyed
when it went out of scope, but the xInfoSet which references it was used
afterward.
