patriceac 074a14f056 Second batch of fixes for search models
Addresses the issues reported by JeLuf:
- - gfpgan: the list with models doesn't appear under the <input> box
- merge models: As long as no models are selected, the <input> box is very short.
- When searching for models by name, the width of the model list shrinks and is smaller than the <input> element.

/*
*** SEARCHABLE MODELS ***
Creates searchable dropdowns for SD, VAE, or HN models.
Also adds a reload models button (placed next to SD models, reloads everything including VAE and HN models).
More reload buttons may be added at strategic UI locations as needed.
Merely calling getModels() makes all the magic happen behind the scene to refresh the dropdowns.
HOW TO CREATE A MODEL DROPDOWN:
1) Create an input element. Make sure to add a data-path property, as this is how model dropdowns are identified in auto-save.js.
<input id="stable_diffusion_model" type="text" spellcheck="false" autocomplete="off" class="model-filter" data-path="" />
2) Just declare one of these for your own dropdown (remember to change the element id, e.g. #stable_diffusion_models to your own input's id).
let stableDiffusionModelField = new ModelDropdown(document.querySelector('#stable_diffusion_model'), 'stable-diffusion')
let vaeModelField = new ModelDropdown(document.querySelector('#vae_model'), 'vae', 'None')
let hypernetworkModelField = new ModelDropdown(document.querySelector('#hypernetwork_model'), 'hypernetwork', 'None')
3) Model dropdowns will be refreshed automatically when the reload models button is invoked.
