test: print stack immediately avoiding GC interleaving

`require(mod)` does not keep the mod in require cache if
mod throws synchronously. This fixes the tests to print
the stack immediately in case that source map cache could
be cleaned up when the CJS module is reclaimed by GC in
the next event loop tick.
