CHANGE DESCRIPTION

Problem:
We do not return original error if primary not found.

Cause:
Short explanation of the root cause of the issue if applicable.

Solution:
Logs were added.
For GetLatestCommitTimestamp log was added, since we use this error message in switch statement:

switch {
				case errors.Is(err, PrimaryPodNotFound) && localCr.Status.State != pgv2.AppStateReady:
					log.V(1).Info("Primary pod not found, skipping WAL watcher")
				case errors.Is(err, LatestTimestampFileNotFound):
					log.V(1).Info("Latest commit timestamp file not found", "file", LatestCommitTimestampFile)
				case errors.Is(err, LatestTimestampIsBeforeBackupStart):
					log.V(1).Info("Latest commit timestamp is before backup start timestamp")
				default:
					log.Error(err, "get latest commit timestamp")
				}
