[snowpatch] [PATCH] settings: remove unnecessary import and associated warning

[Andrew Donnellan]

Remove the unused toml::Decoder import - we reference it explicitly, which
is better.

Signed-off-by: Andrew Donnellan <andrew.donnellan at au1.ibm.com>

This fixes building on rustc 1.7+ (as we have #![deny(warnings)] on).
