[BUG] Intent builder adds a space before TP parts that start with an apostrophe when adding a new TP

[frrleone]

When using the intent builder to add a new training phrase as the one shown below, the builder adds a space between the annotated part and the following part whose text starts with the possessive "'s":

"phone's not working" where "phone" is annotated with ProvidedProductLine

Expected Behavior

Adding the tp as follows:
intent_builder.add_training_phrase(["phone", "'s not working"], ["ProvidedProductLine", ""])

should result in a tp "phone's not working" where "phone" is annotated with ProvidedProductLine

Current Behavior

Adding the tp as follows:
intent_builder.add_training_phrase(["phone", "'s not working"], ["ProvidedProductLine", ""])

results in a tp "phone 's not working" where "phone" is annotated with ProvidedProductLine

Possible Solution

Check if a part starts with the possessive "'s", and, if it does, do not add a space before it. This may be true in other situations as well, for example "," and "?" (these may already be accounted for, I haven't seen them, just a thought.)

@frrleone Great catch. For now this method does not take into account any special character to decide whether to add spaces or not.
Can you provide an example training phrase that includes "," and "?" ?
@kmaphoenix any other characters we should be concerned about?

@MRyderOC Perhaps we should check all ending punctuation: ., !, ?

I think ', , should cover the majority of other cases.
