TagInput - preset v-model OptionsPropItem values aren't displayed properly

[joeyberkovitz]

Overview of the problem

Oruga version: 0.9.2

Description

If using a taginput with OptionsPropItem entries, the values are handled properly when added via autocomplete. If preset via v-model upon the taginput creation with an OptionsPropItem object provided to the v-model, it tries to display the entire object instead of just the OptionsPropItem label

Hey, the value of the v-model is only the value declared on the value attribute of an OptionsPropItem object, not the whole object. So the OptionsPropItem is a wrapper of the real value of an option and the associated label (and some other attributes if needed).

A more detailed description of the options prop and its declaration types and behaviour will surely follow in the docs!
