Fixes/warns about false positives for E0932 undefined-argument-value rule (#1160 #1161)

If the keyword call contains = character but is not keyword argument, it may trigger E0932 rule:

    Push Buttons    C${expression}=
    Get Text    xpath=(//h4)[5]    *=    min
    Get Text    xpath=(//h4)[5]    ==    min

After the fix we are ignoring some of the cases (such as names that would be invalid argument name).

Thanks to @Lakitna for providing fix.
