NNS1-3094: Make projects without neurons clickable again

[dskloetd]

Motivation

In #5202 I made projects without neurons not clickable.
But this makes it not possible to stake those tokens.
We are still working on a way to stake tokens from the projects table but this doesn't need to be part of the MVP.
So we want to make all projects clickable again for now.

Changes

Give every TableProject a rowHref regardless of neurons.

Tests

1. As we may go back again on this once there is a way to stake from the projects table, I kept the structure of the tests the same but just changed the expectations.
2. Tested manually at https://qsgjb-riaaa-aaaaa-aaaga-cai.dskloet-ingress.devenv.dfinity.network/staking/
