### Describe the issue
Warning messages are not displayed when running bitcoin-qt 0.14.2 and 0.14.99 with -disablewallet.
It might be better to always display them.

E.g. on MainNet the "This is a pre-release test build - use at your own risk - do not use for mining or merchant applications" is lost

On TestNet also the "Warning: unknown new rules activated (versionbit 28)" is missed
