In my ever-growing list of test failures, I was seeing this one intermittently.
```
Running 2nd level testscript pruning.py...
Initializing test directory /tmp/testY5ypCv
Warning! This test requires 4GB of disk space and takes over 30 mins (up to 2 hours)

```
After digging into the test, I found that the code is waiting 10 seconds for blk00000.dat to be deleted, and then throwing this failure if it still exists after 10 seconds.
I increased this amount, had the script print the actual time taken, and ran the test a few more times. The time taken ranged between 8 to 12 seconds. So, I feel that this timeout is too short.
After changing the timeout to 30 seconds, the test passes consistently.
(cherry picked from commit 3469911c89a48dd2fefe4d1c2a0c176256e14ee0)
I made a subclass of QMessageBox that disables the send button in
exec() and starts a timer that calls a slot to re-enable it after a
configurable delay.
It also has a countdown in the send/yes button while it is disabled
to hint to the user why the send button is disabled (and that it is
actually supposed to be disabled).
It looks like travis is using the `travis.yml` from the branch, but runs
the test script from the branch merged into master. This causes
pull requests created before the QA tests python 3 transition to fail.
This temporarily reverts fa05e22e91
(#7851). It can be restored when this is no longer an issue.
The example local paths for "Building fully offline" have an extraneous ".git". This caused an error when trying to run gbuild, like this
fatal: '/home/user/bitcoin.git' does not appear to be a git repository
fatal: Could not read from remote repository.
This commit fixes that.
