Make user-defined repository parameter of ArtifactResolver constructor work

[ufolr]

Sometimes the local maven repo may not be ~/.m2/repository .
And In my area, by some network reason we can't connect to the official maven repo, or the official repo is too slow to use. I have to use a mirror repo to speed up the downloading.

When I construct an ArtifactResolver Object with user-defined local repository and remote repository mirror, it can't resolve the pom.

    String localRepo = "D:/Maven/.m2/repo";
    String mavenCenterMirror = "http://mirrors.cloud.tencent.com/nexus/repository/maven-public/";
    ArtifactResolver artifactResolver = new ArtifactResolver(localRepo, mavenCenterMirror);
    File pomFile = new File("src/test/poms/maven-core-3.0.4.pom");

Here is a full test code to replay the issue #20

I find this is because, in function MavenProject getMavenProject(File pomFile), it always use the default repository

request.setLocalRepository(lrs.createDefaultLocalRepository());
request.setRemoteRepositories(Arrays.asList(new ArtifactRepository[] {lrs.createDefaultRemoteRepository()}.clone()));

So I make this PR to set the user-defined repositories to the request, and I exchange the order of repositories handle to make sure the user-defined remote repository to use first.

By doing this, we can make below Plugin Config property of presto work.

maven.repo.local
maven.repo.remote
