S390 Linux is failing tests ColumnFamilyOptionsTest.cfPaths (#7853) 

Summary:
Fix ColumnFamilyOptionsTest.cfPaths and OptionsTest.cfPaths in 6.15 branch (and probably other branches including master)

has_exception variable was not initialized which was causing test failures and incorrect behavior on s390 platform (and maybe others as variable content is undefined).

adamretter please take a look.
