#1814 Remove textbox from callout in TooltipsLab

[blewjy]

Fixes #1814

Previously, there was a textbox added to the generated callout shape from TooltipsLab which may make things complicated for the user. This textbox has been removed in this PR and for any text, user will use the shape's default textbox instead.

@blewjy should we still focus on the textbox of the callout after it is created?

The reason for this is to have a visual cue for the user to input his text directly on the shape.

Another way is to have a default text to the callout shape as well such as "Tooltip"

What do you think, Prof @damithc?

@ChesterSng Personally I don't think it is necessary to focus on the shape's textbox after the callout is created, because it is possible that the user may want to put other things inside the textbox other than text, for e.g. images.

Nevertheless I did give it a try and when trying to select the TextFrame of the shape, it seems to result in like a space character that is being highlighted for some reason, instead of being just a blinking cursor as expected... Typing immediately will revert it back to normal, i.e. there is no actual space character there.

If we want we can also choose to just select the callout shape

The text in the textbox will overflow the callout. I think you should make the callout shape resize when text overflows like in ELL. @blewjy

Prof @damithc, should there be default text in the callout shape like in here:
