jsreport cli start: detect jsreport using normal node resolution

[bjrmatos]

our code to detect the installed jsreport dependency works great in normal apps, but when using it inside a monorepo (like npm workspaces) it fails. this is because we just search the jsreport dep in the current cwd, but in a monorepo the deps are installed in different location, we currently have some fallback code that uses normal node.js resolution but i don't remember why we do it just at a specific case, perhaps we just did it to prevent such fallback going to the wider audience because it was not common to have the node_modules somewhere at a higher level (monorepos were not popular before).

we should probably review this and update a bit the logic.
