Fix specs

[klobuczek]

Made travis configuration changes to make build pass.

Fixes #

This pull introduces/changes:

• Memory configuration changes
• Used extremely long sleep after neo4j:start as in some cases the startup process took over 1 minute, this has to be fixed with a better ready detection strategy in rake neo4j:start (another day in another PR)
• Refreshed the tested ruby and neo4j versions
• Removed identical spec block
• exluded spec directory from coveralls, we should measure the code percentage the specs cover while the specs code itself should not be measured as in my case above removing an identical block of specs which were actually hit reduced the percentage of hit lines. Now the coverage is reported much lower but that is the correct number. Once this PR is accepted the future deltas will be adequate.
