[Flow Exporter] Fix missing template when sending first record

[zyiou]

fixes vmware/go-ipfix#235
fa.templateIDv4 and fa.templateIDv6 are not assigned with any value when first exporting the template records, which caused sanity check not getting passed when sending first record.

E0804 17:01:13.684657 1 flowaggregator.go:392] Error when sending expired flow records: callback execution failed for popped flow record with key: &{10.10.0.1 10.10.1.7 6 48022 4739}, record: &{0xc0002e9aa0 0xc00007a8c0 true 0 true true true}, error: error when doing sanity check:process: templateID 256 does not exist in exporting process

This PR fixes issue above by assign template ID before exporting templates.

In the above description, do you mean the template ID is not assigned with any value rather than an incorrect value. Is that correct?
