fix(interpreter): resolve state file path before chdir

The state file path is resolved to an absolute path before
temp_working_directory() changes the working directory. A relative
state file (e.g. the default state.kore) would otherwise be looked
up inside the temp dir, causing krun to fail with "File does not exist".
