Fix early dev app

[vedhav]

Fixes the error reported here

Changes:

1. Uses proper parent-key mapping in the join_keys so the filter panel provides the valid data to the modules.
2. Standardise the library calls across the apps.

Thanks @vedhav

Should be re-deployed in ~10 mins to test. Can be tested in the same link: https://genentech.shinyapps.io/nest_early-dev_dev

apologies that I jumped into the already closed PR
may I ask: why this particular change?
AFAIK sparkline is a supplementary module package - it's not required for data loading part (as opposed to dplyr, scda etc. which are correct here in this context). Therefore I would expect it to be at the beggining of the app.R script and not inside within().

(same for safety/app.R)

[vedhav]

I had a misconception about this package. I remember that some app had error/warning when this library was not loaded. I think we can remove it.

[vedhav]

I thought that loading this library would improve the variable browser module.

[pawelru]

That's right. It's needed for the variable browser. I got the same understanding. But the position is quite unusual now because you moved the library into the teal_data(...) %>% within(<here>) and usually we have modules libs load outside of this at the top of the script.
