Steps to reproduce:
# Open attached project (test-replace-ibp.zip)
# Switch to iOS and make a build
# Check the resulting directory, notice there is a couple additional files created during the PostProcessing build step (TestTextFile.txt and TestEntitlementsFile.entitlements)
** As an extra test, you can add any files to the project directory manually after the build.
# Go back to Unity and create a second build, choose the same folder the first build was made to and select "Replace" when prompted

Expected result: TestTextFile and TestEntitlementsFile should not exist in the replaced build as PostProcessing script only creates them for the first build. Manually added files should be deleted as well.
Actual result: TestTextFile and TestEntitlementsFile, as well as any manually added files are still present after the second build.
