Silence Error log when AddressBook code is not installed

[blukat29]

Proposed changes

In the chains without AddressBook installed at genesis,

• Until v1.10.2, only an INFO log is printed:

  INFO[09/25,05:53:52 Z] [44] The addressBook is not installed. Use empty stakingInfo
  

• Starting from v1.11.0, ERROR logs are printed, clogging the log even at a high log level.

  ERROR[09/25,05:56:38 Z] [44] failed to update stakingInfo              staking block number=0 err="failed to call AddressBook contract. root err: no contract code at given address"
  ERROR[09/25,05:56:38 Z] [44] unable to fetch staking info              blockNum=3
  

This PR reverts to v1.10.2 behavior.

• This PR does not affect Cypress and Baobab because AddressBook is installed there.
• This PR does not affect service chains with RoundRobin or Sticky proposer policy
• This PR affects service chains with WeightedRandom proposer policy in the log message perspective, but the proposer selection procedure should not change.
