Slightly increase the default timeout for precondition assertions (#17)

# Slightly increase the default timeout for precondition assertions

## ♻️ Current situation & Problem
This PR increases the default timeout from 0.01s to 1s. In the last few
days, tests were sometimes failing as XCTRuntimePrecondition failed to
result in a precondition in the specified timeout. Therefore, we
increase the default timeout to a less restrictive value.

## ⚙️ Release Notes 
* Increase default timeout from 0.01s  to 1s for XCTRuntimePrecondition.
