Thanks to Stephan for helping with the test environment setup:
sbergman@redhat.com: Do the same "set UserInstallation to user profile dir in
test/user-template" in UnoInProcess's setUp as is done in
test::BootstrapFixtureBase::setUp (unotest/source/cpp/bootstrapfixturebase.cxx)
for CppunitTests. That way, these tests all use the workdir/unittest/
UserInstallation concurrently, but they at least do not run into the gotcha in
SubstitutePathVariables::SetPredefinedPathVariables
(framework/source/services/substitutepathvars.cxx) to only set the
PREDEFVAR_USERPATH if PATH_EXISTS.
