Hide calltip when a matching ) is written up to the starting point where it's shown

[ccordoba12]

Right now if you write

li = [1, 2, 3]
(max(<1>li)<2> + 6)<3>

a calltip is shown when the cursor is in <1>, but it's not closed when you write ) in <2> but instead is closed in <3> when that last ) matches the first ( in the line.

@dalthviz, please fix this.
