[IMP] sale_mrp: increase test delta

The test was comparing a scheduled date was correctly computed.
The runbot build 363053 failed because runbot12 is a bit slower and computed
the delay in 2 seconds instead of the 1 previously tolerated.

Increase the delta to 10 seconds.

The delay is a matter of days. Having a difference of 1, 10 or even 100 seconds
should be equivalent functionnaly.

Having a 100 seconds delay could indicate a serious performance issue though...
