[basicprofiles] Fix handling of multiple $DELTA conditions

[jimtng]

There was a bug when having multiple DELTA conditions, resulting in pematurely saving the previous accepted value.

Example:

$DELTA > 1, $DELTA < 10:

• An initial input 50 will be accepted (correct behavior)

• Second input of 60 will pass $DELTA > 1 (60 - 50 is greater than 1)

• Here, the accepted value was incorrectly saved to be 60 before checking the next condition

• When the next condition is checked, the input of 60 is compared against the acceptedvalue (now 60), so the delta is 60 - 60 which is less than 10.

• The correct behavior should be that input 60 is compared against the accepted value of 50, so 60 - 50 which is not less than 10.

Only after all conditions are checked and met should the accepted value be updated.

Please backport to 4.3
