Bad response when app is not used for some time

[ivo-stefchev]

When I use it first time in the day - I get 502 bad gateway.
It is only the first time. After that works fine.
Was not able to reproduce locally. Only in production. I'll try to reproduce one more time when I have time.

This is annoying, because there is no error message in the app and you need to click again on different trolley/bus and then again on the one you want to see the route of interest.

I see what is happening. The server crashes on bad request. SofiaTraffic api has a cookie that expires in 7200 seconds and credentials are reset after 3 hours. The app crashed and is restarted and new credentials are obtained. Maybe this is on purpose.

I do have a restart on crash for the service, but I do not rely on it for this bug.
I hadn't noticed that the xsrf token expires before.
It should be handled and reset properly, probably somewhere in cache/index.js.

I see, getCache() gets called daily and it updates the token, but if it expires in 3h we get the problems anyway.

The simple solution be to just lower that time. It would be a bit better to just refresh the token more frequently, not the whole cache.

I simply adjusted the interval in 79c984e.
We extract some data from the same query we use to obtain the token anyway.
