Fix Gradle plugin logic for removing provided artifacts

The new ResolvedArtifact-based minus implementation was checking the
wrong Set when deciding whether or not a ResolvedArtifact should
be included in the result. This was leading to provided dependencies,
that should have only been packaging in WEB-INF/lib-provided also
being packaged in WEB-INF/lib.

The WarPackaging tests have been updated. In addition to checking that
WEB-INF/lib-provided does not contain anything that’s unexpected, they
also verify the contents of WEB-INF/lib

Fixes #1187
Honour existing java.awt.headless configuration

Previously, SpringApplication would set the java.awt.headless system
property even if it had already been set. This commit updates
SpringApplication to honour any existing configuration when setting
the property.
