assign n/NAME g/GROUPNAME got small issue when use 'g/ g/'

[nus-se-bot]

A similar problem which already existed in the create group command

assign n/Bernice Yu g/ g/

assign n/David Li g/ 1 works means can have space after prefix

Again, this behavior is rare and will not affect other fucntions, just need care about special case

This is working correctly as intended. As we mentioned in the user guide, under the feature section: If a parameter is expected only once in the command but you specified it multiple times, only the last occurrence of the parameter will be taken.

In the case of assign n/Bernice Yu g/ g/, it is treated as the user has specified the parameter multiple time and will take the last occurrence and which in this case, has no input and as such, display the correct message.
