Fix scoring methods running when not using Docker

[gcroci2]

Running the webapp without Docker following the guide in the readme, and configuring the .toml file to download data from POP (using root = "platform:MSV000079284") leads to an error when I try to select either spectra or BGCs data from the webapp UX. In particular, when I click "Show scores for selected spectra" (same for clicking "Show scores for selected BGCs") this error appears on the console:

The first row of the tables shouldn't be selected since it contains - values and it's not a meaningful data point. Probably it is generated during the parsing of the PoDP data. If selected, the webapp source code throws this error. Will be fixed by #2

We will develop a new dashboard from scratch.
