matchms networking Identifier key is not an optional variable

[chufz]

An error occurs when matchms networking is used without any entry for the Identifier key. However, it is marked as optional in the GUI.

Additionally, the user needs to know that what metadata might be in the metadata of the mgf /msp with capital letters will be transformed to a variable name with lower cases in the json file with the similarity matrix.

Following error occurs:

@chufz seems like this is already implemented - can you double check?
