Fixed broken relative path

My Maven build failed with the following error message:
[ERROR] The build could not read 1 project -> [Help 1]
[ERROR]   
[ERROR]   The project br.gov.frameworkdemoiselle:demoiselle-se-parent:2.3.1-SNAPSHOT (/Users/ahe/dev/repos/github/demoiselle/framework/parent/se/pom.xml) has 1 error
[ERROR]     Non-resolvable parent POM: Could not find artifact br.gov.frameworkdemoiselle:demoiselle-extension-parent:pom:2.3.1-SNAPSHOT in sonatype-nexus-snapshots (https://oss.sonatype.org/content/repositories/snapshots) and 'parent.relativePath' points at wrong local POM @ line 44, column 10 -> [Help 2]

I forked the repository and fixed the broken relative path (see attached commit) so the build succeeds.
