Title: Fix spacing in relation error message

Just came across this error in my usage of Bookshelf.js, and noticed it was missing a space in the error log. Kinda bothered me, so I thought I'd just fix it.

Before:
`A valid target model must be defined for the users belongsTorelation`

After:
`A valid target model must be defined for the users belongsTo relation`
