RenderBugsTest>>#testForward: checks for timing, leads to timeouts on slow CI

[MarcusDenker]

testForward checks that an operation takes a certain time:

testForward
	"If the bug exist there will be an infinte recursion."

	| t |
	cases := {(t := TransformationMorph new openCenteredInWorld)}.
	self shouldntTakeLong: [ self assert: t forwardDirection equals: 0.0 ]

This is a problem, as the machines that run the CI job are virtualized and can have very wonky timing characteristics.

Myabe #shouldntTakeLong: should use a higher value for timeout if running on the CI.

we could even think about removing the class RenderBugsTest. I am not that of a fan of tests that test for specific fixed bugs (as opposed to unit tests that are added that fail due to a bug).

Tests like RenderBugsTest can be useful, but as soon as they mean work I am tempted to remove them.

This is fixed
