last used pair across all pages

[zavelevsky]

fixes #1331

When visiting the following pages: trade, explore (by pair), simulate, create strategy - the selected pair becomes the default pair.

Note - the current behavior is buggy. If you start to create a strategy and select a pair that doesn't exist yet it becomes the default pair, even if you don't complete the strategy creation - ending up with a bad "empty" experience in other pages. It can also be more problematic with imported tokens etc.

I personally think that strategy creation shouldn't dictate the pair - or it should only take place once the strategy was created - or only if the pair already exists.

• [x] explore page cannot handle tokens with no pair flow:
  1. go to create strategy
  2. import this token 0x809FF4801aA5bDb33045d1fEC810D082490D63a4
  3. go to trade -> it identify there is no data for the token pair and indicate "no data"
  4. go to explore expected: identify there is no data for the token pair and indicate "no data" as we do for a pair with no strategies (here) actual: there is no token indication in the search url and the page is stuck on endless loading.
