TAB key does nothing in single-value mode when enforceWhitelist is true

This issue is similar to #725.

Basically, using "TAB" to navigate to the next input element does not work in single value select mode when enforceWhitelist is also set as true. Can be observed in demo page.

I think I found the root cause,

tagify/src/parts/events.js

Lines 216 to 218 in e2a0578

	if( this.settings.mode == 'select' && this.settings.enforceWhitelist && this.value.length ){
	e.preventDefault()
	}

Changing that to the following worked for me,

if( this.settings.mode == 'select' && this.settings.enforceWhitelist && this.value.length ){
    if (e.key != 'Tab') {
        e.preventDefault()
    }
}

Thanks for catching. No need for double-"if" statements, it should be done inside the same one :)
