Current behaviour

First time bitcoin-cli uptime is called, output is always zero.

Expected behaviour

Expected behavior should be first time invocation of bitcoin-cli uptime shows the actual bitcoind uptime.

Steps to reproduce

On Linux:

1. ./build/bin/bitcoind -regtest -daemon
2. sleep 10
3. ./build/bin/bitcoin-cli -regtest uptime

Output is zero, while non-zero is expected.
