Empty only search input on results page, not entire table:first
Clean itd search input when navigating between pages
Fix #2
Set Sammy.raise_errors to true in constructor
Merge branch 'develop'
Clean itd-search-input only after first page change

Sometimes "location-changed" event handler is called before
actual route handler and input is emptied before isOnSearchPage
set to true.

So let's just not empty input on first page load no matter what this
page actually is.
