G34 with BL-Touch leads to T0 position shift and possible crash

[Buriaku]

Description:
At the end of a Z-align with a BL-Touch via G34, the T0 tool head position may be assume to be its home, thus shifting it to the right. If another probe move or T0 followed by a G0/G1 move is performed after that, without performing G28 X0 or similar, T0 may crash into T1. This seems to only happen, when T1 is selected as the active extruder previously.

Steps to reproduce the behavior:

1. T1
2. G28
3. G34
4. T0
5. G1 X0

Expected behavior:
T0 should either return to it's home position or be the current toolhead with it's current position.

Workarounds:
1)
T0
G28
G34

G28
G34
G28 X0
