Move FolderCreationDialog into the OCC namespace

[ivaradi]

Compilation has started to fail recently with the following:

                 from /<<PKGBUILDDIR>>/obj-x86_64-linux-gnu/src/gui/nextcloudCore_autogen/mocs_compilation.cpp:24:

This patch attempts to fix it by moving FolderCreationDialog into the OCC namespace.

Isn't the problem more that FolderCreationDialog isn't in the OCC namespace?

[ivaradi]

That sounds reasonable and seems to work too (now really...)

@ivaradi @er-vin Good catch indeed. My bad for overlooking this. Many thanks.
