fix: [stix1 import] Fixed galaxy tag_names fetching from TTP names

- Using the techniques identifier to look for tag
  names when the name does not match any known
  galaxy name
- Prevents the galaxy names to be skipped when
  the provided TTP name is given with the
  identifier and the technique name in an inverted
  order (`Spearphishing Attachment - T1566.001` VS
  `T1566.001 - Spearphishing Attachment`)
