If inputSearchString is given, but component is not focused, the dropdown appears

[matteotrap]

Steps to Reproduce:

• Create a ReactSearchAutocomplete
• Provide an inputSearchString to the component
• Do not focus on the input field

Expected Result:
The dropdown should not appear, as the input field is not focused
The dropdown should appear only if the component is focused.

Actual Result:
The dropdown appears despite the input field not being focused

When I enter a search and then click somewhere else, the drop-down disappears for me.

It disappears if you click elsewhere, but not if you Tab to the next field. The dropdown stays open.
