[FIX][INTEGRATION] Bug fix in merging integration MR

• The integration branch name when a new MR is created actually contains the repository name, while the script that is performing the merging of the branch was using the recipe name. Aligning the behaviour of the two scripts.
• Handle GitLab exception when no MR pipeline is created.
• Insert Mediatek handling in pipeline retriggering function.
