Searching for Pets for an Application

[devinpile]

As a visitor
When I visit an application's show page
And that application has not been submitted,
Then I see a section on the page to "Add a Pet to this Application"
In that section I see an input where I can search for Pets by name
When I fill in this field with a Pet's name
And I click submit,
Then I am taken back to the application show page
And under the search bar I see any Pet whose name matches my search
