Parse error, search results empty, because Rubberduck directory missing from %TEMP%

[cxw42]

RD v2.1.1 in Winword x86, Win10 1709 x64. Installed as local admin, but running as a non-admin user.

I had a parse error with no results, a la #2915. In the TRACE log, I found:

I looked in C:\Users\username\AppData\Local\Temp, which is %TEMP%, and found there was no Rubberduck subdirectory. I created 'C:\Users\username\AppData\Local\Temp\Rubberduck in Explorer without errors. After that the parse worked fine.

We should possibly ensure that that folder exists before using it... The fix should be rather simple, especially considering that we should definitely have write access there

Note that the fix in the upcoming PR is specific to the issue of RUBBERDUCK_TEMP_PATH not existing. I'm assuming there are other "unsafe" file writes elsewhere in the code that need Path.Exists tests.
