Fix fee in example contracts

[foxpy]

This PR also fixes bash test scripts and makes them more beautiful. Try them out!

It is currently a little tricky to test because of issues in ICQ relayer, which I didn't fix yet (I will do that later).
Instructions:

1. the usual, go to neutron:main and run make init && make start-rly, wait until hermes starts printing messages like these:

2023-03-29T08:51:00.533853Z TRACE ThreadId(44) spawn:chain{chain=test-1}:wallet{chain=test-1}: wallet balance amount=99999999998927 denom=untrn account=neutron1mjk79fjjgpplak5wq838w0yd982gzkyf8fxu8u
2023-03-29T08:51:00.890361Z TRACE ThreadId(47) spawn:chain{chain=test-2}:wallet{chain=test-2}: wallet balance amount=99999999995571 denom=uatom account=cosmos17dtl0mjt3t77kpuhg2edqzjpszulwhgzuj9ljs

2. go to neutron-query-relayer:main and replace .env contents with following lines:

# This is an example env configuration for running the relayer with `make dev`

3. now run ICQ relayer using export $(grep -v '^#' .env | xargs) && make dev
4. go to neutron-sdk:fix/example-contracts-fee and run make build
5. go to neutron-sdk:fix/example-contracts-fee, cd into scripts folder. Now, you want to run tests exactly in this order: ./test_ibc_transfer.sh, ./test_interchain_txs.sh, ./test_kv_query.sh and finally ./test_tx_query.sh. Do not restart relayer or node between tests, or you will trigger bugs in ICQ relayer. Once again, I will fix these bugs soon…

Don't worry, these tests are designed to be run individually, I am asking you to run them in exact order only because of bugs in ICQ relayer.

scripts doesn't work:

++ neutrond tx wasm store ../artifacts/ibc_transfer.wasm --from demowallet1 -y --chain-id test-1 --gas 50000000 --gas-prices 0.0025untrn --broadcast-mode=block --keyring-backend=test --output json --home ../../neutron/data/test-1/ --node tcp://127.0.0.1:16657
++ jq -r '.logs[0].events[] | select(.type == "store_code").attributes[] | select(.key == "code_id").value'
...
invalid Bech32 prefix; expected cosmos, got neutron: invalid request
+ code_id=

seems like the nodes ports are not as expected
