Covr coverage issue with websocket and bitops

[amar-v1]

The package coverage test of Websocket package fails with gc() collection error.

Another package bitops that get hung in 'consistency.R' test, while executing package_coverage.

In both the cases the .so file size were different ( i.e. covr build) from R CMD INSTALL. Looking into covr makevars flag are different from devtools (Makeconf).

══ Failed tests ════════════════════════════════════════════════════════════════
── Failure ('test-client.R:209:3'): WebSocket object can be garbage collected ──
collected is not TRUE

actual: FALSE
expected: TRUE
── Failure ('test-client.R:443:3'): WebSocket persists after reference is gone, and can be GC'd after connection is closed ──
finalized is not TRUE

actual: FALSE
expected: TRUE

Could you please assist?

P.S: The package coverage test on covr (3.6.5) fails.
