Change git repos paths

• Read/searched the docs
• Searched past issues

Before all tasks are stored in data/{tid}/*
Now they are stored in data/tasks/{tid}/* and data/data/{tid}/*.
But if I create a task with a repos, all repos data are still saved in data/{tid}.
Probably we should save them somewhere else to escape confused repository structure.
