Proposed changes

After merging this PR, the bid bundle will be mined if extracted.

Bundle logic

We explicitly do not consider the empty bundle (see #ExtractBundlesAndIncorporate)

The auction module requires the additional boolean field in bundle: TargetRequired. If it's set to true, the bundle will be executed only when both conditions I) it's next to target, ii) target has been executed successfully are met (see #shouldDiscardBundle, IsConflict).

After extracting bundles from each module, it cooperates bundles by target tx (see #CoordinateTargetTxHash). It changes the order of bundles and makes them "linked" by updating the target tx hash to the last tx id of the prior bundle.

Now, the bundle is considered to be removed if target has been popped and TargetRequired == true (see #FindDependentBundleIdx)
