Introduce tech.getDefaultMakeCommand() which depending on the returned value ('build'/'create') tells bem make to use bem build or bem create when BundleNode has no specific create-<tech>-node method defined (close BEM-1300)
Move getDefaultMakeCommand() check logic to createDefaultTechNode(); return 'build' in the getDefaultMakeCommand() base implementation
Remove the create-min.<tech>-node() methods from the test project
Fix codestyle
Merge pull request #486 from bem/BEM-1300
