Bad Callsign / Country

[teamcoltra]

There are 61 entries with a space before the entry for "callsign". These correlate to the callsign and country being wrong. I'm guessing these were imported improperly from another data source and not caught. I'll work on a fix for this.

Also I think we should change the format from "alias":"\N", to a more standard "alias":"", which would save space and also fit with how all the other empty fields are. This might need to be another issue but this project seems quiet enough to have them both here.
