[FIX] project: default focus set on sub-task title

Issue:
      When user add sub task then first field is focused.
Fixed:
    In this commit, we have made the title the default focus so that the user does not
    have to click manually and time will also be saved.

Steps:
     - Install project app
     - Active Task Dependencies
     - Create task and add subtask
