Improve ContributionType checking #499
Description
Problem Description
Disclaimer: This issue may be based superseded or incomplete knowledge.
AFIK the computation of the ContributionType.GEOMTRY_CHANGE is computation intensive. That's why, if you are not interested in that type, you should use the OSMContribution.is(ContributionType contributionType) method instead of getContributionTypes().
Yet, this method cannot check for empty ContributionType and as #113 was unfortunately closed, I will still have to check for GEOMTRY_CHANGE to filter empty contribs.
Expected Solution
Add a method to check for empty ContributionType.
