It may get wrong signatures from pyi file

[ChenZhongPu]

It seems that jedi-language-server would read a package's __init__.pyi to support its auto-completion. But sometimes, it may wrongly regards functions as variables.

For example, numpy.log is defined as log: _UFunc_Nin1_Nout1[L['log'], L[10], None], so jedi-language-server regards it as a variable. But in fact, it is a function.

BTW, VSCode's pylance is able to give proper hint in this case. Can jedi also do so?
