test: check if reaction editor trigger a variable change on load

Currently when we load a reaction from RXN in the reaction editor the variable seems to be changed in-place by the module.

My issue is that when loading the reaction the coordinates sometimes change and in the ELN this triggers a change in the entry forcing to save again and again and again ... (sometimes we never reach the state 'saved').

@targos Could you help me to find a way so that when loading a new reaction it does not trigger in place ?

@lpatiny Can you check that what I pushed works as expected (with the molecule editor too)?

[targos]

I did not check your theory about coordinate changes. This only ignores events that are not related to explicit change of the molecule by user interaction (for example loading the structure, or just hovering atoms/bonds with the mouse)
