3545: try unrad sooner

The test that was added used to hang while simplification occured;
The equation was f(q) + g(m) where f(q) was

-4*sqrt(m**2 + m**2/(4*q**2) - 2*m*q - m/(2*q) + q**2 + 1/4)

and g(m) was

sqrt(16*m**4 - 16*m**3 + 8*m**2 + 8*m*sqrt(4*m**4 - 4*m**2 + 8*m + 1) +
24*m + 4*sqrt(4*m**4 - 4*m**2 + 8*m + 1) + 4)

Trying to solve this for q gave solutions whose op count was 2920 and
unless check and simplify were off, seemed to hang the process.

A much better result is obtained (op count 16) by removing *all*
radicals, not only those containing the symbol of interest but takes
9 seconds.
