chai-should: improve contain transformations

[kristerkari]

Hello,

When transforming a large test suite I noticed that the .to.contain transformations are not done very well when there are function calls involved.

In the case when the argument for expect() or .to.contain() is a function call, it would be better to simply transform .to.contain() => .toContain() to avoid any problematic results, which is what my changes do.

Since in Jest's .toContain works on strings and arrays, it should not be needed to transform .to.contain to anything more complicated when we don't know what the result of the function call is.

A real example from the codebase that I'm transforming:

expect(getLink("en")).to.contain(encodeURIComponent("test client name en"));

...gets transformed to:

expect(getLink("en")).toEqual(expect.arrayContaining([encodeURIComponent("test client name en")]));

...and after these changes:

expect(getLink("en")).toContain(encodeURIComponent("test client name en"));
