fix: task status loop

[pateljannat]

Issue:

if flt(self.progress) == 100:
	self.status = 'Completed'

if self.status == 'Completed':
	self.progress = 100

The above code snippet was causing a loop in Task doctype.

Steps to Replicate:

1. Create a task.
2. Mark it as Complete. Save
3. Change the status to Open. Save.
4. The status should remain as Open on save.
