Fix forecast accuracy values and improve performance
Forecast accuracy should be based only on the most recent predictions.
Generally consider measurements and predictions older than 14 days as
outdated and irrelevant. This also implies a performance gain, since it
saves a full scan of gauge_measurements and the extra index for this
purpose.
Adding an extra subquery level for calculation of the forecast accuracy per
row instead of the function call as a FROM item saves a (nested loop)
join, which is another performance gain.

Example: ```sh ssh bern@ourdev.intevation.de -L 8180:localhost:8180 yarn serve --port 8180 --public http://localhost:8180 ``` * Build `yarn build` builds the production ready assets to `web` folder. * Build `yarn build-demo` sets the hg revision as a node env var and builds the production ready assets to `web` folder. * Translation * Extract Messages via `make makemessages` * Translations are converted via `make translations` which is executed automatically with yarn serve/build For more information see [developer documentation](./docs/developer.md) * Tests * Unit tests are started via `yarn test:unit` * e2e tests are started via `yarn test:e2e` Vue cli supports the Chrome selenium driver out of the box If you are interested in using the Firefox variant of the driver see [Vue CLI Plugin Docs](https://github.com/vuejs/vue-cli/tree/dev/packages/%40vue/cli-plugin-e2e-nightwatch) and see also [Nightwatch documentation](http://nightwatchjs.org/gettingstarted#geckodriver)
