cypress: Upgrade to 3.5.0

Package source code needs to be patched to fix tests execution on Linux
(courtesy of https://github.com/oscoin/mvp/commit/5f61adddcbade67ad027fff2a2aa163a821d2d3c).

Remove that patching process once cypress 3.5.1 is released
(see https://github.com/cypress-io/cypress/issues/5434).
