reload page after app close - wait - app open, url is incorrectly encoded

This one was weird and took a while to reproduce. I have an app with a search tab. The search is executed and pust transitioned to the results:
```
"type": "$href",
"options": {
"url": "%s/kmap_do_search?q=%s" % (app_base, trend),
"transition": "push"
}
```

the url that the server sees is (for example)

method=GET path="/kmap_do_search?q=claire%20fontaine"

I then re-open the app sometime laster, not immediately, but maybe 20 mins later, presumably iOS has put the app in some hibernate state. Then I re-open the app, the view opens and the foreground action gets called:
```
"$foreground":
"type": "$reload"
}
```
What I see in the server logs now is

method=GET path="/kmap_do_search?q=claire%252520fontaine"

**Notice the double encoding.**

Start by reproducing the delayed iOS app reopen flow using the $foreground/$reload action after a pushed $href search URL. Trace how the URL is handled during reload and verify that the server receives the original query encoding rather than a doubly encoded value.
