    travisCI: replace mono 4.6.1 with 4.6.2
    
    After the switch from trusty to xenial and the removal of some
    old build hacks, the 4.6.1 lane was the only one that was
    failing[1] due to a weird package installation problem which
    seems related to F#.
    
    IIRC the default version of mono in 16.04 and 18.04 is 4.6.2,
    not 4.6.1, so maybe this change may potentially fix this problem.
