This makes SSH projects work with `ssh_connections` that have multiple
paths:
```json
{
"ssh_connections": [
{
"host": "127.0.0.1",
"projects": [
{
"paths": [
"/Users/thorstenball/work/projs/go-proj",
"/Users/thorstenball/work/projs/rust-proj"
]
}
]
}
]
}
```
@ConradIrwin @mikayla-maki since this wasn't really released yet, we
didn't create a full-on migration, so old ssh projects that were already
serialized need to either be manually deleted from the database, or the
whole local DB wiped.
