Levels and Scores not properly calculated, when completing Skill

[Amar-Bolkan]

Completing a Skill doesnt update the current Score and Level correctly.

Findings:

• selecting Team 3 and completing the skill Input Validation increases the Score by one. However reopening the skill doesn't decrease the Score counter. Setting the skill to Achieved again doesn't increase the counter again.
• When changing the skill status the ngOnChanges method in src/main/webapp/app/custom/teams/teams-status/teams-status.component.ts is triggered. However the changes to the AchievableSkill arent contained in the SimpleChanges object.
• Explicitly setting the Skill status in src/main/webapp/app/custom/teams/skills/teams-skills.component.ts Line 224 and Line 235 , before updating the AchievableSkill doesn't effect the content of the SimpleChanges object.
