When .insert() with BBCode into WYSIWYG, surrounding space is removed

[brunoais]

If you try to select some text and include spaces in the selection, then you programatically call .insert() using BBCode (using just the first 2 parameters), the surrounding space around the selection is trimmed out.
E.g:
Assume you have a tag called s which is correctly set to form <s> tags.
If you type:

abc def ghi

if you select (including the space)

def 

Then you call the editor's .insert() like this:

editor.insert('[s]', '[/s]');

you get:

abc <s>def</s>ghi

Instead of:

abc <s>def</s> ghi

This seems to be caused by https://github.com/samclarke/SCEditor/blob/master/src/plugins/bbcode.js#L1871.

I'm not doing anything because I don't really know the reason why that method call is there.
