fix(bugcollect-plugin): always inject xuqmBuildId manifest placeholder for all variants

The placeholder was only set when minifyEnabled=true, causing debug builds
to fail with "no value for <xuqmBuildId> is provided". Moved buildId
injection before the minify guard; mapping upload task registration stays
after it.
