commit 7d72ab59ae1841fecb0f33c938b37234dde75a8f

    Return null correctly from MutablePropertySources#get
    Prior to this commit, MutablePropertySources#get(String) would throw
    IndexArrayOutOfBoundsException if the named property source does not
    actually exist. This is a violation of the PropertySource#get contract
    as described in its Javadoc.
    The implementation now correctly checks for the existence of the named
    property source, returning null if non-existent and otherwise returning
    the associated PropertySource.
    Other changes
     - Rename PropertySourcesTests => MutablePropertySourcesTests
     - Polish MutablePropertySourcesTests for style, formatting
     - Refactor MutablePropertySources for consistency
