Improve VSPSelect usability and responsivity

[guilhermemntt]

This PR improves the responsivity of the VSPSelect and AutoBuyerSettingsModal components by:

• Stretching the account select to adjust the modal width.
• Enabling clicks on the right corner of a VSP option (currently, there's a padding inserted by react-select).
• Inserting ellipsis on long VSP host names.

Also, the small "close" icon should clear the current input only when typing, since it's useless for clearing the selected VSP.

Looks nice. I found only one thing: the tooltips disappeared.

This is how it looks like on master now:

Hey @bgptr, thanks for the review. That last commit solves the issue by detaching the text-overflow from the relative component.
