Test case for bug

When escaping a special character in the project file, e.g. ";" with "%3B",
xbuild seems to resolve the escape sequence and interpret it as if the
actual character was given.

So, for example, if I'd like to include a file named "MySourc;eFile1.cs", I'd
normally write:
  <Compile Include="MySourc%3BeFile1.cs" />

and expect xbuild to compile the file "MySourc;eFile1.cs". Instead, xbuild
resolves "%3B" to ";" and looks for 2 files: "MySourc" and "eFile1.cs" and
subsequently fails. 

An attached test case illustrates the problem.

This was working in Mono 4.0.1 but as the currently nightly build of Mono 4.3.0 (as of 23/06/15) is no longer working as described in this bug.

In my case %22 is no longer being converted to a double quote, which is being used to escape the possibility of spaces in paths.

Correct interpretation with Mono 4.0.1: https://travis-ci.org/experiandataquality/electronicupdates/builds/68014174#L2094
