when using <c-x><c-t> causes error when there isnt an text

[Gavinok]

When I use the completion mapping when there is no text before it for example a blank line I get this error.

|| Error detected while processing function
|| minisnip#complete[40]
|| E684: list index out of range: 0
|| Error detected while processing function
|| minisnip#complete[40]
|| E116: Invalid arguments for function add

works as expencted when i have typed before using completion. eg if is type f and call completion it will complete with for. as seen in the error it looks like its coming from the call to add.

A temperary solution could be to add this to the start of the completion

if len(l:line) < 1
	return ''
endif
