fix(typeahead): Tab does not behave as click in field at Typeahead component

[Jeetah]

Changing with Tab into the Typeahead field should work as clicking with the mouse into it.
Currently Tab triggers always a search - event if there is nothing in the field (which could also lead to crashes if model is still undefined).
Also Tab in Typeahead popup/dropdown does not behave like Enter/Click.

@Jeetah This should work just fine. What Browser are you using?

[Jeetah]

Chrome - I will test it again with latest version and report back

[Jeetah]

Verified: Tab triggers search event now only if there exists a value in the field. But this makes no sense - it should only trigger if the user enters something new.

PS: Tab in popup works now as expected.

@valorkin
First of all thanks for this great library.
I see the issue for skipping tab event triggering search is fixed and merged. When would this be available through NPM? I see the current(Latest) version still does not have this fix.

Current Typeahead implementation is over complicated, we are preparing for v2 of ngx bs, and first big thing will be completely new, Typeahead

[karthikv-26]

@valorkin Thank you for the quick reply.. Any info when are you planning for the release of v2.. Just to plan things from our end..

[valorkin]

v1.9.2 was last big version of ngx bs,
Starting from tomorrow we will work on v2
I would say v2 will be just a middleware before v3

[karthikv-26]

@valorkin Can there be any patch release for v1.9.x for this tab key handling for typeahead. Because as of now everything else in the typeahead looks stable.

[valorkin]

in v2 will focus trap, and it will be applied to such elements, for more correct keyboard handling
