* Fix last updated time misleading, only show when file content change
or otherwise when it is first created
Fix#1015
* Fix prettier
* - Simplify regex
- Uses shelljs instead of cross-spawn
- Make logic clearer
* Add test when repositories is moved
* Use shell.exec mock
I initially try to mock the whole shelljs. But it returns error
shell.exec is not a function when i try to provide the mockResolvedValue
I think it is because of the inner code of shelljs who run a forEach to
require each of its method which make it a promise. I tried moving the
jest.mock inside beforeAll and also adding babel-dynamic-import but it did
not solve the problem. In the end, I decided to just mock shelljs.exec since
it is the only function used anyway
