Fix: Prevent ":not([mini])" commands from being fired in search-mode

[andischerer]

Since pr #582 commands with :not([mini]) filter in command definition get fired in search-mode editor in case of a missing mini attribute in the atom-text-editor element.

The way how the editor-view was created in the bottom panel has changed from:

new TextEditorView(mini: true)

to:

@editorElement = document.createElement "atom-text-editor"
@editorElement.classList.add('editor')
@editorElement.getModel().setMini(true)

The setMini setter only sets the mini attribute in the model not in the editor-view.

Thanks a lot for catching that!
