Recover a ComponentName from a String that was previously created with ComponentName.FlattenToString. It splits the string at the first '/', taking the part before as the package name and the part after as the class name. As a special convenience (to use, for example, when parsing component names on the command line), if the '/' is immediately followed by a '.' then the final class name will be the concatenation of the package name with the string following the '/'. Thus "com.foo/.Blah" becomes package="com.foo" class="com.foo.Blah".
