acdc/backoffice-frontend unable to build within epi due to issue in install-dfm

[TrueMedHemmo]

karma-jasmine-html-reporter trips a version mismatch.

Steps:

• clone epi workspace
• npm run server
• npm install
• npm run install-dfm
• install fails due to version conflict between dependencies

Solution: Lock karma-jasmine-html-reporter version to 1.5.0 in acdc/backoffice-frontend/package.json
