[CC 1.63][SSP, SMP untested] Bucket Place Bug

Expected result:
turtle picks up liquid immediately next to it.
Result:
turtle picks up liquid below & in front (see diagram)
Diagram:

T = turtle
A = air
S = stone
W = water

T A
S W

to replicate:

1) place turtle
2) dig a hole in front of the turtle
3) put water in the hole
4) give turtle a bucket
5) lua>turtle.place()
