Refrain from using Rspec style expect() syntax

[rx294]

The use of underlying rspec style expect() results in errors similar to:

Message: undefined method `expect' for #<RSpec::ExampleGroups::AnIIS85WebServerMustMaintainTheConfidentialityOfControlledInformationDuringTransmissionThroughTheUseOfAnApprovedTLSVersionTLS11ShouldNotBeDisabledByDefaultCurrentlyTLS11DisabledByDefault:0x0000000008e6c1e0>
Did you mean? exec

We should refrain from this style since this is not officially supported by inspec

Affected controls:

V-76759
V-76769
V-76771
V-76761
V-76757

This should be fixed by 3.0.61

Has this syntax issue been resolved in inspec yet? If so, this issue can be closed.
