include local with "/" as prefix is not recognized

[alexander-matthiesen]

Minimal .gitlab-ci.yml illustrating the issue

structure:

 |- .gitlab-ci.yml
 |- test
     |- nested.yml 

.gitlab-ci.yml

---
include:
  - local: '/test/nested.yml'

common/nested.yml

---
job:
  script:
    - echo "Heya"

Expected behavior "/common/nested.yml" is found

Fallen in the same bug. According to my tests:

	Gitlab.com	gitlab-ci-local
'local: /test/nested.yml'	✔️	❌
'local: ./test/nested.yml'	❌	✔️
'local: test/nested.yml'	✔️	✔️
