On simple strings the utf8 substring copy api call created an assert (#2389)

Browse Source 
When the `jerry_substring_to_utf8_char_buffer` was called
with direct strings the assert incorrectly assumed that the
string is a ref counted string and tried to access the
refcount value resulting in a failed assert.

Added direct string check for the underlying implementation
and created a test case for such simple string.
